This ID Card Holder protects your ID card or badge while keeping it visible. An ID card (sold separately) slides in and stays in place, but is also easy to remove when you need it with a thumb cutout and cutout edge on the back. This rigid plastic card holder can be attached to lanyards, clips or card reels. It accommodates cards up to 0.30mm thick and measures 3-3/8" x 2-1/8" in horizontal orientation.
